7 Introduction vii Introduction This manual contains the necessary information to maintain a bass trombone. The manual covers both bass trombone valve types: Thayer valve and rotary valve. The reader requires a basic understanding of the trombone (less than a year s playing experience) to fully use the manual. The manual does not include chapters on cleaning the valve sections and slide. While possible to perform a basic cleaning by one s self, a chemical bath performed at your local repair shop provides a more effective and complete cleaning. The process of maintaining rotary valves requires significantly less time than maintaining Thayer valves. Allow at least thirty minutes the first time you attempt to maintain Thayer valves. After several times maintaining your instrument, you can complete the full process (slide, valves, tuning slide, and mouthpiece) regularly in less than thirty minutes. The slide needs maintenance at least once a week. Depending on how much you use your instrument, the valves need to be maintained at least once a week, usually at least twice a week. Thayer valves require more frequent oiling than rotary valves, usually at least twice a week. The tuning slides require the least attention. You only need to lubricate the tuning slides every couple of weeks. The mouthpiece, like the valves, depends on your use. You should spray or clean the mouthpiece at least once a week.

11 Thayer Valve Maintenance 3 Thayer Valve Maintenance Disassembly Remove the three tuning slides while pressing down on both triggers. Unscrew the hinges and remove the bell from the valve section. Separate the F and Gb valves.

12 4 How to Maintain a Bass Trombone Gb Valve Remove the screw from the Gb valve ball joint with the flat head screwdriver. Unscrew the valve cone cap and remove the valve from the cone. Wipe the valve and inner cone gently with a cotton rag. Remember to clean in between the valve and the joint. Take the light weight valve oil and liberally apply in between the valve and the joint. Also, apply to the inner cone and the valve itself.

13 Thayer Valve Maintenance 5 Place the valve back into the cone. Replace the valve cone cap and tighten securely. Tighten the braces. F Valve Take the F valve section. Remove the screw from the ball joint. Caution: The trigger is spring loaded. Keep a hold on the trigger while removing the screw to prevent the trigger from snapping back. Unscrew the valve cone cap. Separate the valve from the cone. Wipe the valve and inner cone clean with a cotton rag. Remember to clean in between the valve and the joint as before. Apply the light weight valve oil liberally in between the valve and the joint. Also, apply oil to the valve and inner cone as before. Place the valve back into the cone. Tighten the valve cone cap securely. Tighten the braces. Replace the screw into the ball joint and reattach trigger. Do not over tighten the screw.

14 6 How to Maintain a Bass Trombone Reassembly Replace the screw in the Gb valve s ball joint. Turn the valve section upside down to reattach the Gb trigger to the ball joint. Tighten the remaining braces. Apply one drop of heavy ball joint oil to each of the four ball joints. Work both the F and Gb triggers. Reattach the bell to the valve section and tighten the braces. Push down on the triggers. Replace the three tuning slides.

15 Rotary Valve Maintenance

17 Rotary Valve Maintenance 9 Rotary Valve Maintenance Disassembly Press down on trigger(s). Remove the tuning slides (two for single valve or three for double valve). Release the trigger(s). Single Valve Unscrew the valve cap. Take your light weight valve oil. Apply two to four drops in the middle of the valve. Work the trigger. Screw the valve cap back on. Apply two to four drops down the inner tubing of the valve. Work the trigger. Take your heavy weight ball joint oil. Apply one small drop of the heavy oil to the trigger joint. Work the trigger. Press down on the trigger. Replace the tuning slides.

18 10 How to Maintain a Bass Trombone Double Valve Unscrew both valve caps. Take your light weight valve oil. Apply two to four drops in the middle of each valve. Work the triggers. Take your heavy weight ball joint oil. Apply one small drop of the heavy oil to the trigger joints.. Work the triggers. Press down on the triggers. Replace the tuning slides.

19 Slide Lubrication and Care

21 Slide Lubrication and Care 13 Slide Lubrication and Care Lubrication Unlock the slide lock. Remove the outer slide from the inner slide. Wipe the inner slide off with a cotton rag. Make sure to wipe off old slide lubricant. Take your slide lubricant.

22 14 How to Maintain a Bass Trombone Slide Grease Apply a small amount of grease to the bottom of each side of the inner slide. Gently rub the grease onto the inner slide with your hands. Replace the outer slide onto the inner slide. Note: Bass trombones have dual bore slides. Make sure to replace the side of the outer slide with the lock onto the side of the inner slide with the lock. Work the slide back and forth. Take your spray bottle. Spray a generous amount of water on the inner slide. Work the slide back and forth again. All in One Lubricants Apply a small amount of lubricant to the bottom of each side of the inner slide. Note: Each lubricant is slightly different. Read the package for specific directions. Replace the outer slide onto the inner slide. Note: Bass trombones have dual bore slides. Make sure to replace the side of the outer slide with the lock onto the side of inner slide with the lock. Work the slide back and forth. Spray a small amount of water onto the inner slide if the slide feels a little sluggish. Work the slide back and forth again.

23 Mouthpiece Care

25 Mouthpiece Care 17 Mouthpiece Care Mouthpiece Spray Remove the mouthpiece from your instrument. Take your mouthpiece cleaning spray. Spray once around the outer rim of the mouthpiece and twice inside the mouthpiece. Wipe the mouthpiece with a cotton rag. Run the rag through the shank of the mouthpiece. Spray once around the outer rim again and twice inside the mouthpiece. Let the spray cleaner evaporate on the mouthpiece and air dry

26 18 How to Maintain a Bass Trombone Mouthpiece Boiling Boil a pot of water. Take your mouthpiece brush. Run water through the mouthpiece while the water boils. Run the brush through the mouthpiece and shank. Brush the outer rim of the mouthpiece and inner cup. Place the mouthpiece in the boiling water. Let sit for ten minutes to kill any germs. Let water cool before removing the mouthpiece. Mouthpiece Polish (optional) Grab the silver polish and a rag Gently dampen the rag. Apply a small amount of polish with the rag on any tarnished spots on the mouthpiece. Use only on the outer part of the mouthpiece, away from the rim or where you will put your lips. Rinse under warm running water. Dry with clean rag..

27 Tuning Slide Lubrication

29 Tuning Slide Lubrication 21 Tuning Slide Lubrication Preparation Press down on both triggers. Pull out each of the three tuning slides from the valve section. Set the tuning slides down on a cotton rag. Take another cotton rag. Wipe both ends clean. Make sure to remove any old grease. Lubrication Take the tuning slide grease. Apply one drop of grease on the bottom of each end of the tuning slide. Repeat two more times for the remaining tuning slides. Grab the F valve tuning slide next. Push down on the F trigger and slide one end of the tuning slide into one side of the F valve. Work the tuning slide up and down, spreading the grease. Remove the tuning slide.

30 22 How to Maintain a Bass Trombone Keep the trigger depressed. Put the other end of the tuning slide into the outer side of the F valve. Work the tuning slide up and down, spreading the grease. Keep the trigger depressed. Remove the tuning slide and replace the slide with both ends correctly now. Grab the Gb valve tuning slide next. Push down on the Gb trigger and slide one end of the tuning slide into one side of the Gb valve. Work the tuning slide up and down, spreading the grease. Remove the tuning slide. Keep the trigger depressed. Put the other end of the tuning slide into the outer side of the Gb valve. Work the tuning slide up and down, spreading the grease.

31 Tuning Slide Lubrication 23 Keep the trigger depressed. Remove the tuning slide and replace the slide with both ends correctly now. Replace the main tuning slide. Work the slide up and down, spreading the grease. Push all tuning slide back in.
